Abstract
The present application relates to a kind of compressor, including compression cylinder, compression piston, compression connecting rod and compensation force generating device, the compression piston is movably arranged in the compression cylinder, the compression connecting rod is connected with the compression piston, compensation force generating device is used to generate a compensation force related with compression piston displacement during the reciprocating motion of the compression piston, the compensation force is opposite in the compression stroke with the direction of thrust of working gas to compression piston, in suction stroke, with the direction of thrust of working gas to compression piston same.It is also related to the Stirling refrigerator equipped with the compressor.The present application can effectively adjust the pressure fluctuation influence of working gas in the refrigerator to compression piston by setting compensation force generating device, reduce the motor rotor torque fluctuation caused by gas force fluctuation due to the movement of compression piston, so as to reduce the current fluctuation of refrigerator, improve the temperature stability of refrigerator.
